Im thinking some of the wires may be in the wrong place in the power block? When it arrived it had a few out so i have followed the head unit guide on here and put them in the right place (i think) problem is i connect it to my corsa B blocks (they do fit) and it wont power on?? Though there is 3 blocks all togther to connect to and the head unit only has 2? CDM7874RB model.. (the cd changer one)
Here is a link to a photo of the back of the head unit... and help mucho appreciated guys!

there is three on the car bacause 1 runs the mfd so ignore that 1 the fuse is in the car behind the little panel near your right knee best thing to do is if your interior light aint working they are on the same fuse you will know its gone
other than that get the test light out and wire it to the car cause it looks like the wires have been played about with

yes if you have a 12v feed at the yellow and red pin and a 12v ground those three cables should allow you to put the head unit, a commone problem with these alpine is people burn the earth tracks out try plugging the aerial lead on see if it powers up grounding through the aerial
